This idea is to recover as much otherwise wasted energy during this process as possible and convert it to useful energy. The way the new systems achieve this is very simple and clever, (in lay mans terms) on starting the vehicle the vehicles software instructs the alternators voltage to rise higher than normal, usually around the 14.9V + level, this is to return the energy into the battery which has just been depleted a little during the start up process, however, there is another part of the program which says to t
